"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/smc: initialize close_work early to avoid warning\n\nWe encountered a warning that close_work was canceled before\ninitialization.\n\n WARNING: CPU: 7 PID: 111103 at kernel/workqueue.c:3047 __flush_work+0x19e/0x1b0\n Workqueue: events smc_lgr_terminate_work [smc]\n RIP: 0010:__flush_work+0x19e/0x1b0\n Call Trace:\n ? __wake_up_common+0x7a/0x190\n ? work_busy+0x80/0x80\n __cancel_work_timer+0xe3/0x160\n smc_close_cancel_work+0x1a/0x70 [smc]\n smc_close_active_abort+0x207/0x360 [smc]\n __smc_lgr_terminate.part.38+0xc8/0x180 [smc]\n process_one_work+0x19e/0x340\n worker_thread+0x30/0x370\n ? process_one_work+0x340/0x340\n kthread+0x117/0x130\n ? __kthread_cancel_work+0x50/0x50\n ret_from_fork+0x22/0x30\n\nThis is because when smc_close_cancel_work is triggered, e.g. the RDMA\ndriver is rmmod and the LGR is terminated, the conn->close_work is\nflushed before initialization, resulting in WARN_ON(!work->func).\n\n__smc_lgr_terminate | smc_connect_{rdma|ism}\n-------------------------------------------------------------\n | smc_conn_create\n\t\t\t\t| \\- smc_lgr_register_conn\nfor conn in lgr->conns_all |\n\\- smc_conn_kill |\n \\- smc_close_active_abort |\n \\- smc_close_cancel_work |\n \\- cancel_work_sync |\n \\- __flush_work |\n\t (close_work) |\n\t | smc_close_init\n\t | \\- INIT_WORK(&close_work)\n\nSo fix this by initializing close_work before establishing the\nconnection."
